IGBT Thermal Management system
Kev muag khoom loj hlob ntawm cov tsheb tshiab lub zog thiab qhov xwm txheej tam sim no ntawm chip tsis txaus, ua ke nrog qhov tsis paub tseeb ntawm kev sib kis yav tom ntej, kev lag luam ntawm IGBT tseem nyob rau hauv lub xeev nruj. Zoo ib yam li lwm yam khoom siv hluav taws xob, txhawm rau ua kom nws ua haujlwm tau zoo, nyab xeeb thiab ruaj khov, kev tswj xyuas thermal thev naus laus zis rau IGBT module yog qhov txuas tseem ceeb tshaj plaws hauv kev tsim thiab siv cov khoom tshiab.
IGBT yog dab tsi:
IGBT (insulated gate bipolar transistor) yog ib yam khoom siv hluav taws xob semiconductor. Nws lub npe Suav yog "insulated gate bipolar transistor", uas yog tsim los ntawm BJT (bipolar junction transistor) thiab MOSFET (insulated gate field effect transistor). Raws li cov khoom siv hluav taws xob tseem ceeb ntawm kev hloov hluav taws xob thiab kev tswj fais fab, IGBT hu ua "CPU" hauv kev lag luam hluav taws xob hluav taws xob.
Thermal tswj rau IGBT Modules:
Qhov tsis ua hauj lwm ua rau feem ntau IGBT fais fab semiconductor modules muaj feem xyuam rau cov cua sov. Yog li ntawd, kev ntseeg siab ntawm IGBT kuj tau cuam tshuam los ntawm kev lag luam thiab kev kawm, thiab tau dhau los ua qhov kev tshawb fawb hotspot tam sim no. Cov txheej txheem tswj thermal rau IGBT modules tuaj yeem muab faib ua kev tswj hwm thermal thiab sab nraud thermal tswj. Hauv cov ntawv thov tshwj xeeb, vim tias muaj peev xwm ua kom sov loj ntawm lub tshuab ua kom txias thiab cov khoom siv semiconductor substrate, tsuas yog maj mam hloov qhov kub thiab txias tuaj yeem them rov qab, yog li kev tswj xyuas sab nraud yog tsim nyog rau kev sib tshuam ntawm qhov kub thiab txias. Rau qhov hloov pauv kub ceev, nws raug txiav txim siab los kho qhov ntsuas hluav taws xob ntsig txog qhov kub thiab txias hauv qhov system, uas yog, kev tswj hwm thermal sab hauv, kom cuam tshuam ncaj qha rau qhov sib txuas kub.
Internal thermal tswj:
Lub tswv yim tseem ceeb ntawm kev tswj xyuas thermal sab hauv yog hloov pauv qhov poob ntawm IGBT module kom du qhov sib txuas kub hloov pauv los ntawm kev thauj khoom lub zog hloov pauv. Txog tam sim no, cov kws tshawb fawb tau tshawb nrhiav ntau lub tswv yim kev tswj hwm thermal, suav nrog kev hloov pauv zaus, kab sib chaws tiv thaiv, lub voj voog ua haujlwm, lub zog hluav taws xob thiab lub zog hluav taws xob, thiab ua pov thawj lawv qhov ua tau zoo theoretically thiab sim.
Sab nraud thermal tswj:
Cov txheej txheem tswj kev thermal sab nraud ntawm IGBT module feem ntau yog siv los them cov kev hloov pauv ntawm qhov kub thiab txias los yog tswj qhov nruab nrab ntawm qhov sib tshuam, thaum kev tshawb fawb txog kev hloov pauv qhov kub thiab txias yog tsawg.
Zoo ib yam li lwm cov khoom siv hluav taws xob, kev ua haujlwm zoo, ruaj khov, yooj yim thiab kev cog lus txias yog qhov tseem ceeb rau kev tsim cov khoom siv IGBT kom ntseeg tau tias lawv muaj kev nyab xeeb thiab ruaj khov. Tshwj xeeb tshaj yog nrog kev nce ntawm IGBT module zog ceev, qhov hnyav daim ntawv thov ib puag ncig, thiab kev txhim kho kev ntseeg tau thiab lub neej, rau IGBT module, nws cov thermal tsim thiab thermal tswj technology yog qhov tseem ceeb tshaj plaws txuas hauv kev tsim thiab siv cov khoom tshiab.
